Friends fans finally got to see their favourite cast reunite again after all these years, and the highly-anticipated event didn't disappoint! On Thursday, Friends: The Reunion officially made its debut on HBO Max, full of emotions, laughter, and surprises! Here are some of the highlights from the 2-hour long special!

Friends cast gets split into teams for trivia about the show

Friends stars Jennifer Aniston, Courteney Cox, Matt LeBlanc, Matthew Perry, Lisa Kudrow, and David Schwimmer faced off in some fun trivia! The game was staged in the same way as season 4, episode 12 ("The One With the Embryos"), and saw the cast test their knowledge of all things Friends.

It also included surprise appearances from several celebrities who guest starred on the show, including Tom Selleck and Larry Hankin. Ultimately, it was the team of Aniston, Cox, and Kudrow who emerged victorious— and as it turns out, no one actually knows what "Chandler's" job is!

Schwimmer and Aniston admit to having had a mutual crush

Friends had many fans invested in "Ross" and "Rachel's" relationship— and as it turns out, there was a real-life reason for their chemistry! "The first season, we-- I had a major crush on Jen," Schwimmer revealed. And as it turns out, his co-star said the feelings were "reciprocated"!

However, Schwimmer said that they had both been in relationships at different times, so he and Aniston had been "like two ships passing". Since the two didn't end up getting together off-screen, Aniston shared that they "channeled all of our adoration and love for each other" into the romance between their characters!

Friends cast comes together for table read of two episodes

Friends saw many beloved episodes over the course of its 10 seasons, so it made sense to revisit a few of them with the gang back together again! While the HBO Max special itself was unscripted, fans got to see the cast gather around a table to read segments from two episodes.

Season 4, episode 1 ("The One With the Jellyfish") and season 5, episode 14 ("The One Where Everybody Finds Out") were both featured in the segment. The cast appeared to enjoy the experience, seen enthusiastically immersing themselves in their iconic roles and bursting into laughter several times!

Kudrow joins Lady Gaga in a lively duet of "Smelly Cat"

Kudrow's character "Phoebe" is known for her quirky musical stylings, including the unforgettable song "Smelly Cat". Kudrow began singing the ditty before Gaga entered, causing the audience to cheer. The pop star channeled Kudrow's character "Phoebe" with her outfit and carried a guitar of her own.

The two stars then sat on the couch together, Kudrow watching in awe as Gaga performed her own rendition of the song! The duo were even joined by backup singers, bringing fans "Smelly Cat" in a way they'd never heard before.

Friends fashion show sees celebs wear iconic costumes

Friends featured many memorable costumes over the years, and the reunion special saw several outfits revisited with the help of some celebrity models! Cara Delevigne was the first to appear, seen in both "Rachel's" pink bridesmaid dress and the "Holiday Armadillo" costume.

Cindy Crawford squeezed into "Ross's" leather pants, and Justin Bieber also put on the character's "Sputnik" Halloween costume. Perhaps the most iconic moment of the segment though was when Matt LeBlanc stepped out onto the runway, rocking "Joey's" hilarious overdressed look!
